Life in a Drop of Water

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Within the setting of a crime scene investigation, biochemistry beginners analyze organic compounds as a means of determining "Who dunnit." They use a brown paper test for lipids, glucose test strips and iodine to identify carbohydrates,...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

Water is an interesting substance that all living things need to survive. Learners focus on the characteristics of water as they create a list of words related to water and then incorporate them into descriptive paragraphs. They then use...

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...

Students recognize whether one wants to drink water, swim in it, or for the health of the organisms living in it. They prepare different water samples to observe and collect samples regarding the water quality.

Students perform an experiment to measure the density of tap water vs. salt water.

By testing your local water quality, you will be able to compare your results with students around the world. Register your class, and follow the project instructions. Additional teacher resources, references, and Ask-an-Expert sources...
